1. 5th
year exam
1-The correct use of dental elevators needs
a- Correct grip
b- Point of application
c- Proper fulcrum
d- Force magnitude& DIRECTION
e- All of the above
2-Surgical extraction needs
a-A mucoperiosteal flap
b-decrease resistance of bone &tooth or both
c-Correct application of force magnitude &direction
d-All of the above
3- A correct mucoperiosteal flap must include these criteria except
a-broad base
b-proper extension
c-includes both mucosa &periostium
d-short extension
4-Preoperative radiographs are essential before surgical extraction for the following except
a-relation to vital structures
b-number of roots
c-curvature of roots
d-presence of pathological lesions
e-any systemic disease of the patient
2. 5-Applicaton of force of unknown magnitude and direction can lead to:
a-fracture of the tooth
b-fracture of the jaw
c-breakage of the elevator
d-All of the above
6- Cryer elevator is preferred than cross bar elevator because of:
a-less force magnitude
b-less fracture of the jaw
c-more controlled force
7- Debridement of the wound includes
a-removal of tooth debris
b-removal of any parts of fillings
c-removal of detached bone fragments
d-All of the above
8-The straight elevator is used to primarily luxate the lower third molar if:
a-the roots are distally curved
b-the second molar is present-
c-the first molar is missing &the second molar is to be extracted
d-All of the above
9-The straight elevator is not used to luxate the lower third molar if:
a-the roots are mesially curved
b-the roots are straight&long
c-the first molar is missing
3. d-Allof the above
10- Abnormal excessive an lead to:
a- Fracture of the tooth
b-fracture of the jaw
c-breakage of the elevator
d-All of the above
11-Suturing of the wound has the following advantages:
a-decrease wound infection
b-decrease pain
c-Rapid healing
d-All of the above
